Noise-Free Sound Audio Isolator for Common Ground Interference Elimination​

1.Product Description

Isolation of common ground interference between devices, elimination of current sound, filtering effect, sound noise reduction and so on.

Determine whether the noise is caused by common ground:

1, the use of headphones and car MP3, car navigation AUX (3.5mm interface) connected, if there is no noise heard from the headphones at this time, you can confirm that the noise of the car equipment is caused by common ground.

2, use the audio line to connect the battery-powered mobile phone, or MP3(pay attention to the mobile phone, MP3 do not connect with any power supply in the car, such as the phone) and the AUX of the car console, and play the music of the mobile phone, so that there is no noise, you can confirm that the noise in the past is caused by common ground.

3, computer, power amplifier, audio, CD: the use of passive headphones inserted in the computer to listen to no noise, the use of mobile phones inserted in the power amplifier, audio test, if there is no noise between the two, the basic judgment is caused by common ground.

4, after starting the car, the installed power amplifier has the current sound, some models will also appear the larger the throttle, the larger the current sound, this product can solve this problem.

5, there is a current sound between the power amplifier and the speaker or speaker, you can install this product between the power amplifier and the speaker.

6, the laptop computer connected to the projector at the same time to the power amplifier to produce noise, you can connect the laptop adapter power supply or battery, at this time unplug the power amplifier noise disappeared, or unplug the projector the same noise disappeared, then you can add a common ground isolator between the headset hole and the power amplifier to eliminate noise.
